A cavity wall has two separate walls constructed with a gap in between the two walls . The two leaves of cavity walls can be of equal thickness if it is non load bearing wall.
The cavity is normally between 5 cm to10 cm.Cavity walls give good sound property.It gives better thermal insulation.
Cavity walls are constructed to prevent thetransmission of dampness to the inner walls.It prevents moisture.They prove to be economical.

• This type of partition are cheapest as well Plain brick as considered strong and fire resistant .partition •Bricks are reinforced with iron stropsReinforce d brick or steel bars. partition • It consists of brick work within the frame Brick work of wooden members namely studsnogging (vertical members)and nogging piecespartition (horizontal member).
Can be plain orreinforced. It may be cast in site or built from panels or blocks precast in advance. This partition are rigid and stable along both vertical and horizontal directions.
These may be made from sheet glass or hollow glass bricks.Sheets of glass are fixed in the framework of wooden members dividing the entire area into a number of panels.
Glass block adds to the architectural beauty and also provide good day light.They are soundproof and fire proof.Needs care and mainteance.
Thistype of partition walls consists of a wooden framework either supported on the floor below or by side walls. Such partitions are not fire-resistant and the timber forming the partition is likely to decay or be eaten away by white ants. The major advantage of using this partition is light in weigth though costlier.
Wooden frame is used to fix the this sheets for the partition. They are lighter in weight , thin and cheaper. To make it more strong ,specially manufactured asbestos slabs are used. Fire-resistant and makes it have good heat and sound insulation properties.
They are made from clay , terra-cotta or concrete. They are light in weight , rigid ,strong , economical and good insulation. They are available in variety of sizes.

Sand is mixed with fevicol and applied on the wall. Sand are available in different colors like orange, blue, brown, etc. It gives the desired look, dull or smooth. It is not affected by fire. It is very expensive and it cannot be easily removed.
•Is available in a variety of colours. It is mostlyLimestone used on exterior walls. •It is natural concrete of sand grains. It looksSandstone and feels sandy. •A sedimentary rock that splits easily into thin sheets with smooth surfaces; it gives good Slate interior flooring or outdoor paving.
Metals are mostly used for their decorative and hygienic qualities. Metals such as copper and aluminium are decorative. Stainless steel in the form of tiles can be used in kitchens where they present a durable, easily cleaned hygienic surface in areas where splashing is likely
It is a board/tile covering the lowest part of an interior wall. Its purpose is to cover the joint between the wall surface and the floor. It covers the uneven edge of flooring next to the wall; protects the wall from kicks, abrasion, and furniture; and can serve as a decorative moulding.
White wash is made from pure fat lime (white stone lime) or shell lime. White wash may be applied in specific number of coat until the surface presents a smooth and uniform finish.
Themajor disadvantage of wood wall is that it does not provide proper insulation and makes a lot of noise but on the other hand it has an advantage as it does not need any type of painting or plaster.
Paint is the simplest finish to apply to walls. Paint is applied on timber, metal, brick or other material in the form of a liquid which on drying forms a thin cover on the painted surface. The most important function of the paint is to provide protection or decoration.
Wall papers are available in a variety of colors and design. They are preferred in bedrooms, living rooms or drawing rooms. The wall papers are just struck on the plastered surface with the help of an adhesive.
Fiberglass:- It is low cost and has good insulating values. It is available in batts, blankets and loose. Mineral wool:- most often called rock wool. Its insulating qualities are good. Cellulose:- this is an inexpensive insulation made of recycled materials most notably newspapers.
Mica:- this product is made from the mineral mica. The insulating qualities are only fair. Silver wool:- It consists of wood slivers retardant. The most common wood appears to be cedar that is resistant to rot and pests. The insulating qualities are quite good.
Wall panels are available which are sound absorbing panels that mount directly to the walls or ceilings. They are designed to increase speech intelligibility by reducing reverberation and echoes.
An ‘isolated’ stud wall is build incorporating resilient bars, acoustic mineral wool and sound proofing mats , in front of the existing wall. Sound proofing mats are also available which dramatically reduce the airborne noise transmission of standard lightweight structures. Mineral fiberboard is a common substrate used with fabrics, wood or acoustical tile to control the acoustics within the room.
Acoustical plaster, used to finish walls, is made with perlite or vermiculite aggregate that is most often sprayed onto the walls rather than applied by hand. Another product that is available in many sound-absorbing materials is a wall panel. Many are made from molded mineral fibers and covered in fabric that is attached to a standard wall surface.
